ePubPreflight (ePub Style Checking) Released

Paul Norton from Adobe Digital Editions has now released the epubpreflight validation tool. This small utility is meant as a compliment to epubcheck and is used to check that your ePub files are suitable for Mobile devices. There are many guidelines that need to be followed when developing ePub for mobile devices that are not mentioned in the EPUB specs, so this is going to be a very welcome tool.

Here’s a list of things that epubpreflight currently checks for;

• Content files that are empty.
• Content files that are over 300KB.
• Image files that are empty.
• Image files that are over 10MB.

As you can see the list is rather small at the moment but this will grow in time. On the DE blog, Paul also mentions that he would like to see a set of configuration files that could test for specific platforms (ADE, PRS505, conversion to other formats, etc.)

It’s going to be a good number of years yet before mobile devices have the power to parse very large files (images, chapters, etc) so it’s going to be in everyone’s interest to see this tool developed.

ePub books finally reach mass market status

New eBook Standard Now Available For Mass Market Audience was the title from yesterdays WebWire press release on the ePub book catalogue at BooksOnBoard.com. With almost 200 eBooks in the ePub format this is the first real source for mass market books to be released in the new eBook standard.

It’s a little unclear if the ePub versions have DRM restrictions, but as the site states;

DRM Adobe ebooks can be read only on Adobe Reader 7, Adobe Acrobat 7, or Adobe Digital Editions [...] We recommend Adobe Digital Editions for Adobe format eBooks, both pdf and ePub versions…

We must presume that they have DRM in place.

The market is still waiting for better ePub readers and until we get those it won’t matter how many ePub books they release. Let’s hope that the Sony Reader (PRS-505) receives its Digital Editions firmware update soon and that other dedicated readers, such as the Amazon Kindle and Cybook follow suit.

Yes, we still have a long way to go but it does look like we’re on the right track.

Adobe release Digital Editions 1.5 - with enhanced DRM flexibility

Adobe Digital Editions has been updated with enhanced DRM support and flexibility, now at version 1.5. Adobe DE is a Flash based, lightweight, internet application used for reading PDF’s and the IDPF’s ePub document formats.

The enhancements to their DRM means that users activate their DRM protection on a named basis, this allows you to move your protected eBooks/eDocuments across platforms and mobile devices, of course we’d rather not have any DRM (or at least just social DRM). There is also a limit of 6 desktop and 6 handheld devices that you can activate, which should be okay for most people in the short term (if TeleRead’s DRM Poll is anything to go by) but over a period of several years we are likely to need to activate more devices than this, particlarly if we have to re-format our OS. We shall have to see what the future holds for those needing to activate more devices.
